Sprinkler irrigation
🔑Key Points:
Drip irrigation
-It is also called trickle irrigation is used in areas with water scarcity and salt problems.
-It involves the slow application of water, drop by drop to the root zone of a crop,  water seeps from these holes drop by drop, hence the name drip irrigation.
-Water-saving 50-70%Â as compared to surface irrigation.
-The difference in water delivery rate between extreme emitters should not exceed 10%
-Water discharge rate is generally 1-4 lit/hr. at 1.5-2.5 kg/cm2 pressure.
-The water use efficiency of drip irrigation is 95%
-Most suitable for widely spaced crops, orchards trees, and greenhouses.
• Advantage of drip irrigation:
-​​Increased water use efficiency
-High crop yield
-Uniform and better quality of the produce
-Efficient and economic use or fertilizer through fertigation
-Less weed growth
-Minimum damage to the soil structure and reduction in soil erosion
-Usage in undulating areas and slowly permeable soil
-Low energy requirement i.e. labor-saving
